In the title compound, [Na(C(6)H(3)Cl(2)O(3)S)(H(2)O)](n), the Na(I) ion is penta-coordinated by three dichloro-benzene-sulfonate anions and two water mol-ecules, forming a distorted trigonal-bipyramidal geometry. The Na(I) ions are bridged by the sulfonate groups and the water mol-ecules, leading to a polymeric layer structure parallel to the bc plane in which O-H⋯O hydrogen bonds are observed.
The title compound, C15H18NO3PS·C6H6, is a rare example of a crystallographically characterized exocyclic phosphiniminium-arene-sulfonate zwitterion, which crystallises as its benzene solvate. The crystal structure shows that the N atom is protonated and that the iminium H atom forms both intra- and inter-molecular hydrogen bonds to the single-bonded sulfonate O atom in an R 2 (2)(4) graph-set ...
In the asymmetric unit of the title salt, C6H9N2 (+)·C7H7O3S(-), there are two independent 2-amino-6-methyl-pyridinium cations and two independent 4-methyl-benzene-sulfonate anions. Both cations are protonated at their pyridine N atoms and their geometries reveal amine-imine tautomerism. In the 4-methyl-benzene-sulfonate anions, the carboxyl-ate groups are twisted out of the benzene ring planes...
conclusions the findings of this study showed that the modification of natural zeolites can achieve higher adsorption capacity for organics. in addition, based on the results, natural zeolite being modified with sds as a cationic surfactant had good efficiency for the adsorption of nom. results the results indicated that sds-modified zeolite showed greatly enhanced adsorption capacity. findings...
A local wastewater treatment plant (WWTP) experiencing poor nitrification tracked down high level of surfactants in the plant’s influent and effluent. The aims of this project were to assess the potential inhibitory effect of surfactants on activated sludge processes. The effect of the presence of TergitolNP-9, TrigetolNP-7, Trigetol15-S-9, dodecylbenzene sulphonate (SDBS) and sodium dodecyl su...
